About tero24.shop
tero24.shop is a free QR code generator built around one idea: your data should stay on your device. Every code is created directly in your browser — the network name, contact details or link you type is never sent to a server. There is nothing to sign up for and nothing to install.
The tool covers 25 QR types — from WiFi and vCard to payments, calendar events and social links — with guidance written for each specific use, in nine languages.
Our approach
Most online QR generators upload what you type to their servers to render the image. We don't. The QR code is drawn locally in your browser using open web technology, which means your passwords, phone numbers and addresses stay private by design. It also keeps the service fast and free to run.
What you can create
Each QR type has its own page with a ready-to-use form and practical notes on what tends to go wrong — encryption settings for WiFi, character limits for vCards, network mismatches for crypto, print sizing for menus and cards. You can download every code as PNG, SVG or PDF, free and without a watermark.
- Private: generated in your browser, nothing uploaded.
- Free: no account, no watermark, no limits.
- Practical: type-specific guidance, not generic filler.
